I thoroughly enjoyed the first book in the series and this one is even better. The characters are incredibly likeable - even Glotka (a particularly nasty torturer) is an interesting and immensely likeable character. You know characters are well written when you aren't sure whether to be sickened by a character or to be cheering him on.
The dialogue is usually funny, interesting and witty. Well written characters, well written dialogue and despite it being the bridging book there are plenty of exciting events. Abercrombie writes battles very well, they feel fast paced.
He is descriptive of the locations in the book, but not overly so - a trap that many fantasy writers fall into. You know what the world looks like but the focus remains on the characters, not banal details.
The book feels fun, the characters are great, it's well paced. Highly recommended!
